Eluate

Liquid that contains dissolved residues and accumulates due to leaching.

In this way aqueous eluates may occur in landfills (s. Disposal site) and carry particles of disposed substances. The concentration of the dissolved, contaminated residues, i.e. the eluate contents of the waste material to be disposed are a decisive factor with regard to their hazard potential in landfills and define the conditions for disposal.
